The present invention relates to the field of food retail equipment, and more specifically, to an intelligent food cooking machine for cooking fresh foods such as fresh noodles or fresh glass noodles.
In recent years, problems in the aspects of food safety and food sanitation hazards are news themes frequently covered by various media nationwide. A means of ensuring catering and food safety has been an important subject that urgently needs to be addressed. As it comes to the twenty-first century and with continuous social progress, people's pace of life is accelerating and living standards are improving. Therefore, various fast foods and food selling manners have emerged. There are numerous street foods, fast foods, instant noodles, deep-fried foods, and the like.
Currently, there are two manners of getting fast foods. The first manner is fast food outlets that involve manual cooking and selling. In this manner, a long time is usually taken, it is inconvenient to buy foods, and food safety is often not guaranteed. There is the risk of cross infection among employees. The second manner is instant foods, especially, instant noodles. This manner is a reluctant choice for many consumers. People often buy instant noodles in convenience stores or street food stalls during travels, business trips or leisure and entertainment. However, there are two obvious disadvantages. First, instant noodles are served in small amounts, lack nutritional value, are mostly deep-fried, and probably contain preservatives. Second, boiled water is required to prepare instant noodles. As a result, the preparation and consumption of instant noodles are severely restricted, and instant noodles have poor nutrition value and unsatisfactory taste. Therefore, an intelligent food cooking machine that can rapidly cook healthy, nutritious, and wholesome foods with a variety of flavors is invented to satisfy people's requirements for healthy foods. The intelligent food cooking machine is convenient to use and time-saving, omits manual cooking and selling, and avoids the risk of cross infection among employees.
An objective of the present invention is to provide an intelligent food cooking machine that has a simple structure and is convenient to use.
To achieve the objective, the present invention provides the following technical solution:
An intelligent food cooking machine comprises a frame. A bowl dispenser opening, a coin slot, a change return slot, and an operation panel are disposed on a panel of the frame. A coin device and a change return device are disposed in the frame. A refrigerator is disposed above the frame. A bowl storage mechanism for storing bowls is disposed in the refrigerator. A separation and fetching mechanism for separating and fetching a bowl is disposed below the bowl storage mechanism. A push mechanism for pushing a bowl is disposed on a side of a lower stop position of the separation and fetching mechanism. A microwave heating mechanism for heating a bowl is disposed in a pushing direction of the push mechanism. A delivery lifting mechanism is disposed on a side, facing the bowl dispenser opening, of the microwave heating mechanism. The delivery lifting mechanism delivers a heated bowl to the bowl dispenser opening.
By means of the foregoing technical solution, a customer performs an optional operation by using the operation panel on the frame. After a coin is inserted into the coin device through the coin slot, the change is returned through the change return slot. Bowls are stored in the bowl storage mechanism. A bowl is separated and fetched from the bowl storage mechanism by using the separation and fetching mechanism. When the bowl is placed in the lower stop position of the separation and fetching mechanism, the push mechanism pushes the bowl to the microwave heating mechanism for heating processing. After heating is completed, the push mechanism pushes the bowl to the delivery lifting mechanism again. The bowl is sent to the bowl dispenser opening by using the delivery lifting mechanism. In this way, a whole process of intelligent heating and selling is implemented, the structure is simple, and the use is convenient. In addition, a constant low-temperature state is kept inside the refrigerator, so that food in the bowl in the bowl storage mechanism in the refrigerator is kept fresh.
A further setting of the present invention is as follows: The bowl storage mechanism comprises a large wheel disc and a wheel disc drive device for driving the large wheel disc to rotate. A rotating shaft is disposed in the central position of the large wheel disc. A plurality of bowl drop holes is circumferentially and evenly distributed on the large wheel disc near the edge. A storage unit for storing bowls is disposed right above each bowl drop hole. The hole diameter of the bowl drop hole is greater than the diameter of a bowl cover. The separation and fetching mechanism is located right below the bowl drop hole.
By means of the foregoing technical solution, the large wheel disc of the bowl storage mechanism is rotatably connected to a bottom portion of the refrigerator by using the rotating shaft. The wheel disc drive device drives the large wheel disc to rotate in a relatively positioned manner. A plurality of bowl drop holes is circumferentially and evenly distributed on the large wheel disc near the edge. A storage unit for storing bowls is disposed right above each bowl drop hole. Each storage unit can store bowls, so that the bowl storage mechanism can store a large quantity of bowls. In addition, each storage unit is independent and corresponds to one bowl drop hole. After bowls in one storage unit are all conveyed, the large wheel disc only needs to rotate by an angle, and another storage unit is aligned with the separation and fetching mechanism again, so as to continue with a conveying procedure. In a conveying process, bowls in different storage units do not interfere with each other, so that the bowl storage mechanism can convey bowls filled with food to the separation and fetching mechanism stably for a long period of time.
A further setting of the present invention is as follows: The storage unit comprises a movable rod and a plurality of positioning rods. The movable rod and the positioning rods are circumferentially and evenly distributed along edges of the bowl drop holes. A starting track is disposed between the movable rod and a neighboring positioning rod. The movable rod can approach the positioning rod along the starting track.
By means of the foregoing technical solution, the movable rod and the positioning rods are circumferentially and evenly distributed along the edges of the bowl drop hole, to form a storage space for placing bowls. The bowls are stacked and sequentially placed in the storage space. In addition, the movable rod may slide towards the neighboring positioning rod through the starting track, to create an opening to the storage space. After the bowls in the storage space are all conveyed, an operator may fill the storage space with bowls again through the opening. The structure is simple, and the operation is convenient.
A further setting of the present invention is as follows: The wheel disc drive device comprises a small wheel disc and a wheel disc drive motor. An output shaft of the wheel disc drive motor is linked to the small wheel disc. The small wheel disc is placed on a side of the large wheel disc. Teeth engaging each other are provided on outer side walls of both the small wheel disc and the large wheel disc.
By means of the foregoing technical solution, the wheel disc drive motor drives the small wheel disc, and drives the large wheel disc to rotate clockwise or counterclockwise. In this way, each bowl drop opening[U1] in the large wheel disc can be aligned with the separation and fetching mechanism, to implement bowl delivery and fetching. The teeth of the small wheel disc and the large wheel disc mesh with each other for transmission. A rotation angle of the large wheel disc can be precisely controlled. In this way, a problem that the bowl drop hole cannot be aligned with the separation and fetching mechanism because of an excessively large or small rotation angle can be effectively avoided.
A further setting of the present invention is as follows: An ultraviolet germicidal lamp and an illuminating lamp are further mounted in the refrigerator. The ultraviolet germicidal lamp and the illuminating lamp are placed on a side of the bowl storage mechanism.

A further setting of the present invention is as follows: The separation and fetching mechanism comprises a bowl separation mechanism and a bowl fetching mechanism. The bowl fetching mechanism is located right below the bowl separation mechanism. The bowl separation mechanism comprises a bowl separation cylinder, and the bowl separation cylinder is located right below the bowl drop hole. A plurality of bowl separation forks and a plurality of bowl separation fork seats for mounting the bowl separation forks are circumferentially and evenly distributed on an outer side wall of the bowl separation cylinder. The bowl separation fork is hingedly connected to the bowl separation fork seat. An upper clamping opening and a lower clamping opening are separately provided in positions on a cylinder wall of the bowl separation cylinder that correspond to the bowl separation fork, and the upper clamping opening and the lower clamping opening respectively fit upper and lower portions of the bowl separation fork. The bowl fetching mechanism comprises a bowl fetching arm and a bowl fetching lifting device for driving the bowl fetching arm to move up and down. A bowl tray fitting the bowl separation cylinder is provided on the bowl fetching arm. When the bowl tray moves upward, an outer edge of the bowl tray presses the upper portion of the bowl separation fork, so that the upper portion of the bowl separation fork sways outward, passes through the upper clamping opening, and is placed outside the bowl separation cylinder, and when the bowl tray moves downward, the outer edge of the bowl tray presses the lower portion of the bowl separation fork, so that the lower portion of the bowl separation fork sways outward, passes through the lower clamping opening, and is placed outside the bowl separation cylinder, so that the upper portion of the bowl separation fork sways inward, passes through the upper clamping opening, and is placed inside the bowl separation cylinder.
By means of the foregoing technical solution, when the bowl tray moves upwards, the bowl tray carries the bowl to move upward. In addition, the outer edge of the bowl tray presses the upper portion of the bowl separation fork, so that the upper portion of the bowl separation fork sways outward, passes through the upper clamping opening, and is placed outside the bowl separation cylinder. Then, the bowl tray moves downward by using the lifting device. In this case, the upper portion of the bowl separation fork is located outside the bowl separation cylinder and is no longer clamped to the bowl, and the bowl continues to move downward with the bowl tray. As the bowl tray keeps moving downward, the outer edge of the bowl tray presses the lower portion of the bowl separation fork, so that the lower portion of the bowl separation fork sways outward, passes through the lower clamping opening, and is placed outside the bowl separation cylinder. In this way, the upper portion of the bowl separation fork sways inward again, passes through the upper clamping opening, and is placed inside the bowl separation cylinder. In this case, the upper portion of the bowl separation fork exactly catches another bowl to prepare for a next time of fetching a bowl from the bowl tray. The structure is simple, and bowls can be continuously separated and fetched. Two neighboring bowls are precisely separated by means of swaying by the bowl separation fork and coordination of the bowl tray, thereby preventing interference during separation and fetching of bowls.
A further setting of the present invention is as follows: A sealing plate for sealing a lower end opening of the bowl separation cylinder is disposed at an interval below the bowl tray.
By means of the foregoing technical solution, each time after completing the action, the bowl fetching mechanism needs to move upward for resetting. The sealing plate on the bowl fetching arm and the lower end opening of the bowl separation cylinder are pressed and sealed, so as to prevent cold air in the refrigerator from leaking from the bowl separation cylinder. In addition, in a standby case, the sealing plate is also in a state of being pressed and sealed to a lower-end flange of the bowl separation cylinder, thereby preventing cold air from leaking, so as to achieve energy conservation and environmental protection.
A further setting of the present invention is as follows: Magnet members are separately provided at upper and lower ends of the bowl separation fork seat. The two magnet members respectively correspond to outer sides of the upper and lower portions of the bowl separation fork. During swaying of the bowl separation fork, the bowl separation fork and the magnet members can attract and stick to each other.
By means of the foregoing technical solution, during swaying of the bowl separation fork, the bowl separation fork and the magnet members can attract and stick to each other. The magnet members steadily attract an outer side surface of the fork, so that the fork cannot freely move or return, and the bowl separation fork is clamped to or separates stacked bowls more stably and effectively.
A further setting of the present invention is as follows: A clamping groove for clamping a bowl and an upper slanted surface fitting a rising and pressing action of the bowl tray are provided at the upper portion of the bowl separation fork. A lower slanted surface fitting a dropping and pressing action of the bowl tray is provided at the lower portion of the bowl separation fork. The upper slanted surface and the lower slanted surface are disposed facing each other.
By means of the foregoing technical solution, the bowl separation fork can be stably and firmly clamped to the bowl by using the clamping groove. When the bowl tray performs rising and dropping actions, the outer edge of the bowl tray presses the upper slanted surface and the lower slanted surface, so that the bowl separation fork sways inward or outward, thereby implementing clamping or separating of bowls. The structure is simple, and manufacturing is easy.

One end of the bowl fetching arm 321 is fixedly connected to the bowl fetching sliding block 3222, and the other end of the bowl fetching arm 321 is fixedly connected to the bowl tray 323, so that the bowl fetching lifting device 322 does not need to be located right below the bowl separation cylinder, and the bowl tray 323 of the bowl fetching lifting device 322 only needs to be coaxially mounted with the bowl separation cylinder.
Each time after completing working, the bowl fetching mechanism 32 needs to move upward for resetting. The sealing plate 324 on the bowl fetching arm 321 and a lower-end flange of the bowl separation cylinder 311 are pressed and sealed, so as to prevent cold air in the refrigerator 11 from leaking from the bowl separation cylinder 311. In a standby case, the sealing plate 324 is also in a state of being pressed and sealed to the lower-end flange of the bowl separation cylinder 311.

The heating drive device 522 comprises a heating slider 5221, a heating lifting track 5222 used for the heating slider 5221 to slide up and down, a heating screw rod, and a heating drive motor for driving the heating screw rod to rotate. A threaded hole is provided at the heating slider 5221. The heating slider 5221 is threaded to the heating screw rod through the threaded hole. The heating slider 5221 is fixedly connected to the sealing tray 521. The sealing tray 521 in the heating lifting device 52 can move up and down smoothly, so that during heating of the bowl[U6], the round hole of the sealing cover plate 512 of the microwave housing 51 and the end surface of the sealing tray 521 are better pressed and sealed, and the reliability is higher.
A positioning piece 54 for aligning the center of the bowl is disposed in the microwave housing 51. A liquid conveying tube 55 for pouring soup, oil, and boiled water into the bowl is further disposed in the microwave housing 51. The positioning piece 54 has a conical tube-like structure. A large end opening of the positioning piece 54 is disposed downward. The diameter of the large end opening of the positioning piece 54 is greater than the diameter of the bowl cover. The conical structure has an automatic alignment function. When the bowl is placed on the sealing tray 521, as the heating lifting device 52 moves upward to stably convey the bowl to the microwave housing 51, if the bowl is not located at the center, the conical structure is used to finely adjust the position of the bowl for automatic alignment, thereby ensuring that the liquid conveying tube 55 can be accurately inserted into a center hole of the bowl.
The microwave heating component 53 mainly comprises a magnetron with a water cooling jacket, an excitation cavity, and a heating control power supply. The power supply is controlled, so that the magnetron with a water cooling jacket and the excitation cavity perform microwave heating work. (The specific structure and working principle of the microwave heating component 53 belong to the existing mature technology, and details are not described herein.) A circulating cooling water tank is mounted below the microwave heating component 53. The circulating cooling water tank is a water storage tank for circulating cooling required by the microwave heating mechanism. A float switch is mounted in the circulating water tank, and is used to control the height of the water level, to ensure that the water tank stores sufficient water all the time and prevent water from overflowing or being used up, thereby fully ensuring normal and effective work of microwave heating. The circulating cooling water tank is mainly used to control the working temperature of the microwave heating component 53 to stay in a specified range, thereby ensuring the service life and function stability of the microwave heating component 53.
A plurality of air outlet holes is provided on a side of the microwave housing 51. The diameter of the air outlet hole is 1 mm. This not only can ensure that air in the microwave housing 51 is exhausted, but also can prevent microwave in the microwave housing 51 from leaking.

A limiting plate 75 is disposed above a position, close to the chopstick dispensing opening 711, on a bottom wall of the chopstick box 71. The spacing between the limiting plate 75 and the bottom wall of the chopstick box 71 is greater than the diameter of a chopstick, and the spacing should not exceed 1.5 times of the diameter of the chopsticks. Otherwise, chopsticks are easily stuck between the limiting plate 75 and the bottom wall of the chopstick box 71 in the conveying process. An opening groove used for the chopstick pressing device 73 to slide is provided on a side, close to the chopstick dispensing opening 711, of the limiting plate 75.
The chopstick pressing device 73 comprises a press block 731. A chopstick push rod 732 is provided at an upper portion of the press block 731. The chopstick push rod 732 is threaded to the press block 731. This can facilitate adjustment of the position of the chopstick push rod 732. A sliding portion is separately provided on left and right side walls of the press block 731. The sliding portion slidably fits the track. The press block 731 abuts one end of a reset spring by using the sliding portion. The other end of the reset spring abuts the bottom portion of the chopstick pressing track 74. To facilitate positioning of the reset spring, the reset spring is placed in the chopstick pressing track 74. The chopstick pressing track 74 may be formed by alternately disposing a column perpendicular to the limiting plate 75 and the front side plate. The sliding portion is placed in a spacing between the column of the limiting plate 75 and the front side plate. One end of the reset spring abuts the limiting plate 75, and the other end of the reset spring abuts the sliding portion.
The chopstick conveying device 72 comprises a timing belt and a drive motor. A primary timing pulley and a secondary timing pulley are provided on the timing belt. The primary timing pulley and the secondary timing pulley tighten the timing belt, and both the primary timing pulley and the secondary timing pulley are rotatably connected to the left and right side plates by using the rotating shaft. The primary timing pulley and the secondary timing pulley are on a same horizontal plane. An output shaft of the drive motor is connected to the primary timing pulley. An upper end surface of the timing belt and the bottom wall of the chopstick box 71 are on a same horizontal plane. The drive motor is controlled to rotate clockwise or counterclockwise, to implement chopstick delivery and chopstick arrangement.
A slope plate 76 is provided on a side of the bottom wall, away from the chopstick dispensing opening 711, of the chopstick box 71. A side of the slope plate 76 is connected to a rear side wall of the chopstick box 71. The other side slopes downward and toward the timing belt. The sloping angle may be 25 degrees to 45 degrees, and is preferably 35 degrees. In this way, chopsticks can be easily placed in the chopstick box 71. To prevent the chopsticks from dropping, the slope plate 76 abuts an end surface of the timing belt. When chopsticks need to be placed, the chopsticks may be placed on the slope plate 76 first, so that the chopsticks are sequentially conveyed forward. In addition, because the slope plate 76 is disposed, it is also avoided that some chopsticks are placed in the corner of the chopstick box 71 and cannot be conveyed forward.
To ensure that a customer takes a bowl and chopsticks safely, safety light curtains are mounted on two sides of the bowl delivery bin 63. The bowl delivery bin 63 drops and is reset (that is, a safety door is closed) only after the customer takes away the bowl and chopsticks. In a process in which the safety door is not completely closed, if a foreign object enters, the safety door can also stop closing immediately under the effect of the safety light curtains. In this way, the customer is prevented from being injured by pinching and the machine is prevented from being damaged, thereby ensuring safety of the customer and the machine.
A mechanism for measuring and providing soup, oil, and boiled water is further provided in the intelligent food cooking machine of the present invention. The mechanism is a group of measuring pumps. The measuring pumps are sequentially mounted in the frame 1, and are correspondingly connected to related pipes. These pipes are connected to the liquid conveying tube 55, so as to add and pour a specified amount of soup, oil, boiled water, and other required liquid. The boiled water may be provided by connecting a water outlet of a purified water tank and a water inlet of an instantaneous water heater.
In the embodiment of the present invention, a structural principle of screw-rod transmission is used in all the delivery drive device 62, the heating drive device 522, and the bowl fetching drive component 3224, which have similar structures.
The working process is as follows: A customer performs an optional operation on the intelligent food cooking machine by using the operation panel. After a coin is inserted into the coin device through the coin slot, the change is returned through the change return slot. Because bowls are stored in the bowl storage mechanism 2, a bowl is separated and fetched from the bowls in the bowl storage mechanism 2 by using the separation and fetching mechanism 3. The bowl is on the bowl tray 323 of the bowl fetching arm 321 of the bowl fetching mechanism 32. The bowl tray 323 moves down to sequentially pass through the bowl drop hole 211 and the bowl separation cylinder 311. When the bowl is placed in the lower stop position of the separation and fetching mechanism 3, the push mechanical hand 41 of the push mechanism 4 pushes the bowl and places the bowl on the sealing tray 521 in the heating lifting device 52 right below the microwave housing 51. The heating lifting device 52 sends the bowl on the sealing tray 521 to the microwave housing 51 for heating processing. After the bowl is heated, the push mechanical hand 41 of the push mechanism 4 pushes the bowl to the bowl delivery bin 63 in the delivery lifting mechanism 6 again. The push mechanical hand 41 immediately exits and is reset. The bowl delivery bin 63 moves upward to the bowl dispenser opening 14 under the effect of the delivery push rod 61. Because the automatic chopstick dispenser mechanism 7 is provided on the bowl delivery bin 63, in the rising process, the bowl delivery bin 63 drives the automatic chopstick dispenser mechanism 7 to automatically drop chopsticks. The customer takes the bowl and the chopsticks through the bowl dispenser opening 14. In this way, a whole process of intelligent heating and selling is implemented.
